9 Signs He's Not a Cheater Based on science, at least.

Being cheated on is the worst. You feel rejected but also pissed. You don't know who you can trust. Well, scientific studies have narrowed down some traits that are statistically more common in guys who cheat, so here are some signs (not confirmation, obviously) that your guy will never stray.

 1. You bring home the same amount of money.

 A recent study from the American Sociological review showed that partners were less likely to cheat if they were in the same (or similar) income brackets. Men were more likely to cheat if they made a lot more money than their partner, and they were most likely to cheat if they made a lot less. So if you two have similar paychecks, you've got statistics on your side.

2. He's from the Midwest.

According to this poll , Midwesterners are just too well-mannered to cheat on their partners.

3. His friends are also faithful.

People are more likely to cheat if their friends are also cheaters, according to M. Gary Newman, author of The Truth About Cheating . If his friends are trustworthy, it's likely he's trustworthy too.

 4. He feels loved and trusted.

According to a study conducted by Newman, most men don't cheat because they're not satisfied sexually. They cheat because they're seeking emotional satisfaction.

5. He's an extrovert.

 Extroverts are less likely to go along with the influence of others. Research shows that introverts are actually more likely to cheat because they're more likely to agree to someone propositioning them. So even if he's always out there meeting new people, you actually might be safer.

 6. He just seems like the kind of guy who wouldn't cheat.

According to a real study that people spent time on , researchers found that you can trust your gut when it comes to guys who look like they'd cheat. If your gut is telling you "no," then it's a good idea to listen to that gut.

7. He's really into Pantera.

 Yeah, according to this survey conducted by the Mirror (so, questionable), heavy metal listeners are apparently the least likely to cheat.

 8. He comes from a big family.

A survey from adult meet- up site Seeking Arrangements shows that cheaters are usually only children. Ask if he has a sister.

 9. He has a hard time getting it up.

A sad study published in the Archives of Sexual Behavior showed that men who are easily aroused are more likely to cheat, so I guess mark one in the "pros" column for whiskey dick.
